- 8 Claims. v 1

This invention relates generally to mop wringers, but has reference more particularly to the type of portable'mop wringer which is adapted to be supported on a bucket into which the water from the mop is to be'wrung.

A primary object of the invention is to provide a mop wringer of the type described, having improved means for facilitating the mop-wringing operation.

Another object of the invention is to provide a mop wringer of the character described, having means incorporated'therein for supporting .the movable roll in rolling contact with a base member during the initial phase of the mop- Vwringing operation.

A further object of the invention is to provide a mop Wringer of the character described, having means incorporated therein for elevating the movable roll out of rolling contact with the base member during the mop wringing operation, whereby to facilitate rotation of said roll during the mop wringing operation.

A further object of the invention is to provide a mop wringer of the character described, which consists of a minimum number of parts which are inexpensive to manufacture, and which can be easily and quickly assembled at low cost.

A still further object of the invention is to provide a mop wringer of the character described, having manually-controlled rack and gear means for augmenting the rotation of the movable roll during the mop-wringing operation.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a top plan View of a mop wringer made in accordance with the invention;

Fig. 2 is a cross-sectional view, taken on the line 2 2 of Fig. 1, and showing the movable wringer roll in retracted or, inoperative position;

l Fig. 3 is a view similar to Fig. 2, but showing the movable wringer roll in advanced or operative position; ,l

Fig. 4 is a view similar to Fig. 3, but showing a modication of the wringer, and

Fig. 5 is a fragmentary cross-sectional view, taken on the line 5 5 of Fig. 4.

Referring more particularly to Figs. 1 to 3 inclusive of the drawings, it will be seen that a mop Wringer constructed in accordance with the invention comprises a base or frame which is preferably formed from a single length of angle iron bent to a more or less rectangular form to provide sides I and 2, and ends 3 and 4, the ends of said length of angle iron being connected, as by rivets 5, to a clip 6, having a downwardly extending flange l.

The horizontal legs of the aforesaid sides and ends of the base or frame are disposed in a common horizontal plane, thereby facilitating placement of the mop wringeron the upper edge of a bucket or pail B, which` is indicated by dotted lines in the drawings. To prevent lateral displacement of the mop wringer from the bucket, I provide a second clip 8, which is secured, as by rivets 9, to the ends of the angle iron base, in parallel spaced relation to the ange 'I cf the clip 6. By disposing the flange 1 inside the bucket, andv the clip 8 outside the bucket as clearly shown in Figs. 2 and 3, the mop Wringer is firmly secured against lateral displacement. The clips 6 and 8 thus serve a double purpose in that they secure together the ends of the angle iron length to complete the base, and at the same time, provide a means for retaining such base on the bucket. Y

Secured, as by rivets I9, to the vertical legs of the sides I and `2 adjacent the end 4, are brackets or plates II, portions of which extend above such vertical legs to provide bearings for the trunnions I 2 of a stationary wringery roll I3, this roll, it being noted being disposed sufficiently above the horizontal legs of the sides I and 2 to be freely rotatable at all times.

Pivotally secured, as by rivets I4, to the vertical legs of the sides I and 2 adjacent the end 3 of the base, is a foot plate or member I5, of rectangular form, having downturned anges I6 and I1 at the front and rear respectively, and downturned flanges I8 and I9 at its sides.

Pivotally secured, as by rivets 20, to the anges i8 and I 9, adjacent the flange I6, are curved members 2 I, which are interconnected, intermediate their Vends, by a rod 22, so that the members 2l are movable as a unit. The lower ends of the members 2| provide bearings for the trunnions 23 of a movable roll 2li, which is similar in length and diameter, to the roll I3.

A tension coil spring 25 interconnects the central portion of the rod 22 with the central portion of the flange Il of the foot plate I5.

The members 2I are also provided with cam portions 26, the function of which will be presently described.

The members 2| are normally maintained in the position shown in Figs. l and 2 by means of the spring 25, and this position of the members 2l results in maintenance of the foot plate |5 in the position shown in these figures. It will be noted that when the members 2| are in this position, the roll 24 bears'directly on the horizontal legs of the base ends and 2, which legs thus serve as tracks or guides for the roll 2li. It will be further noted that when the roll 24 thus bears directly on such legs, the cam surfaces or portions 26 of the members 2| are elevated slightly above such legs, as is clearly apparent in Fig. 2.

When it is desired to wring a mop, which is diagrammatically indicated by reference. character M in Fig. 3, the mop is placed in the bucket B, and the operator then steps on the Vfoot plate L5, exerting pressure upon the foot plate until the roll 24 .is moved to the mop-wringing position shown. in Fig. 3, after which the operator pulls the mop upwardly ,through the rolls I3 and 24, thereby wringing the mop.

I It will be noted that in theinitial stages .of the aforesaid movement, the roll 24 rolls on the horizontal legs of the sides and 2 of the base, so that the movement of the roll to its operative position is greatly facilitated. If the roll 24 r'emained in contact with the base while in the operative position shown in'Fig. 3, the movement of Vthe mopM would be hampered, due to the frictional engagement of the roll 2'4 with such base, which would resist turning of this roll'. vAs the roll 2.4 approaches its operative position, however, the cam portions 4.2t of themember2| come into engagement with the horizontalY legs of the sides`| and 2, as shown in Fig. 3, thereby elevating the rolllZd above such. legs. This permits the rol1'24 to. rotate freely in its bearings, and, as-a result,.tl1e wringingof the. mop is greatly facil- K.

itated. The` provision of the cam portions25 on the members 2| is therefore a highly important feature of the invention.

lIt will be further-noted that the foot plate l5 and the members 2| form elements of a toggle, which enable a relatively small pressureapplied to the foot plate to be converted into a fairly high pressure of the roll 2,4 against the mop.

After the mop has been wrung, the foot `is removed from theplate 15, and the contraction of Ithe spring `25 then automatically .restores the movable parts tothe position shown in Figs. l and.2.

In cases where mops ofv relatively large size are to be Wrung,'such forv example as mops vdesigned for use inhotels :and oiceibuildings'it is desirable, although not absolutely necessary, to provide means for augmenting the pull on the mop while being wrung. Such means is illustrated in Figs. 4 and 5.

Referring to Figs. 4 and 5, itv will be seen that .the trunnion |:2" at one endof the roll`| 3is eX- tended beyond the'side of the' base 'to provide .a support fora pinion y2, which is .keyed ory other wise rigidlyv .secured tothe trunniomso :as tol be .rotatable with theroll i3, the .pinion being maintainedagainstaxial displacement from the trunnion .by meansof acollar28 and a cotter pin 23.

Welded, or otherwise .secured .to the .side of the base is a trackmember .or guide 3Q .for areciprocable rack 3|, which is in mesh with the pinion 2l, the rack being provided at its upper end with a grip or handle 3.2.

Inthe use of the aforesaid means, as themop is being wrung, the handle of the mop is grasped in one hand, andthe handle 32 of the rack 3| in the other hand, and as the mop is pulled upwardly, the handle 32 is also pulled upwardly, thereby causing the rack to rotate the pinion 2l, which, in turn, causes the roll |3Y to be rotated, thereby facilitating the wringing of the m01). v i

It is to be understood that the forms of my in.- vention herewith shown and described, are to be .taken as preferred examples of the same, and that various changes in thev shape, Size and arrangement o Vparts may be resorted to, Without departing from the spirit of my invention, or the scope of the subjoined claims.
